Data integration based on MapGIS and ASCII code files
Data integration based on MapGIS includes data conversion,data normalization,data fusion,and related research.A syn-thesis of existing research suggests that data conversion has been intensively studied,while there is a lack in studies of data normaliza-tion and data fusion.This study improved the data normalization method based on the complex and extensively applied geological maps,achieving the normalized annotation and color filling for thousands of geobodies at one time.A technical process for data fusion was es-tablished by analyzing the applicable conditions of various commonly used methods for data fusion and making some supplementation.Besides,ASCII code files were prepared for mapping small coal pillars in batches.The results of this study show that improving the da-ta normalization method,establishing the technical process for data fusion,and making full use of ASCII code files can significantly en-hance the efficiency of data integration and broaden the mind for problem solving.
